How Much Does Solar Installation Cost A Look Into Average Prices For Solar Panels
In 2010, an average homeowner in the United States would have paid around $40,000 for a full-size solar panel system for their home. Fast forward to 2021, the average cost for a solar panel installation has fallen 50% to roughly $20,000 .
Breaking down math is pretty simple. Just multiply the price per watt by the size of the system you need for your home: $3.20 per watt times 6,000 watts equals $19,200 there you have the average cost of a solar panel installation for your home. But where exactly do those numbers come from? And are there any local incentives available to slash that price tag even further? Thats what were here to help you understand.
Solar Costs Over Time Continue To Fall
A solar panel system hasnt always been $2.76/W. As recently as five years ago, the cost of solar panels was almost 20 percent higher than it is now:
Prices will likely continue to fall even more in the future. The solar industry is still young, and theres plenty of innovation still to come. As manufacturing and installation processes mature and become even more efficient, solar shoppers will hopefully start to see some of those cost savings impacting their sticker price for solar.
How Much Does A Single Solar Panel Cost
If youre looking to buy your own solar panels and install them yourself, you can expect to pay somewhere between $200 and $250 per solar panel. That doesnt include other costs, like inverters, wiring, and installation, which is why the cost of a full solar panel system installation seems much higher.

Federal Solar Tax Credits And State Solar Incentives
When you own your home solar system, you are eligible to apply for available federal and state incentives and rebates.
In December of 2020, Congress passed an extension of the federal solar Investment Tax Credit , which provides a 26% tax credit against the costs of the purchase and installation of residential solar systems installed between 2020 and 2022. Next year in 2023, that credit will decline to 22% for home solar systems. How much will the ITC save a home solar system owner? For a $20,000 system, the 26% federal credit would be $5,200, compared to $4,400 under the 22% credit.
Several states also offer solar tax credits and solar tax rebates. People who own their solar system and/or battery in participating states may be able to claim these expenses on their local taxes or receive cashback on their installation. While you may be eligible for a solar tax credit or a solar tax rebate with the purchase of a home solar system, please remember that tax incentives are subject to change.
Understanding The Solar Investment Tax Credit

As we alluded to earlier, the ITC has been an overall boon to the expansion and health of the solar industry. As of 2021, the ITC reduces the cost of installing solar panels by 26%, and its a large reason the solar industry has consistently experienced a 42% annual growth rate for the past decade.
Unfortunately, the residential ITC is set to completely expire by 2024, with the ramp down already happening now. Thankfully, solar panel installations costs overall have decreased during the life of the ITC, but the solar panel industry is still preparing for a slowdown in installations in the short-term future. Therefore, if there was any time to consider solar panels for your home, the time is now. The discount is only going to decrease.

Review Your Electric Bill
Solar panels generate their own power and can therefore greatly offset your monthly electricity bill, if not eliminate it. The higher your bill, the more likely youâll benefit from switching. But you should note that electricity rates and usage the main charges on your statement are volatile.
âIf a utilitys electricity prices fluctuate, so could the amount of savings,â says Garrett Nilsen, deputy director for the U.S. Department of Energyâs solar energy technologies office. âSimilarly, if energy consumption changes, the amount of savings can also vary.â

How Many Solar Panels Will You Need
To know how many solar panels you will need, you will want to determine how much electricity you use in your home and the solar panel types installed.
The average house in the United States uses about 900 kilowatt hours a monthroughly 11,000 kWh a year. You can easily calculate your actual usage by looking back at your electricity bills. As a general rule of thumb
- A 3-kWh solar panel system will generate about 3,600 kWh 4,800 kWh per year.
- A 5-kWh system produces about 6,000 8,000 kWh per year.
- A 10-kWh system can produce about 12,000 kWh 16,000 kWh per year.
Depending on the size of the system, the solar panels cost would be between $4,000 and $16,000. Add in another $3,000 to $10,000 for other necessary components, such as racks for the panels, wiring, solar inverter costs, and the total solar panel installation cost would now be closer to $20,000.

Cost Of Solar Panels By State
One of the broadest ways to gauge the overall cost of solar is by looking at the average price of solar panels by state. Our statewide average prices are calculated using market research and data from top brands. These prices can help convey a better understanding of what solar might cost in your area:
Average Cost of Solar By State | Average Cost of Solar Per Watt | Average Cost of a 5kW System After Tax Credit |
Alabama | ||
$2.57 | $9,509 |
Keep in mind that 5kW is a baseline size and near the smaller end of most solar panel installations. Use this figure as a minimum.
Location Of Your Home
Lets get real here: A home in Phoenix will create more solar electricity than one in Portland whether Oregon or Maine even if both homes are completely bereft of trees.5 Geography is essential to the efficient generation of solar power. You can always install solar panels on your roof wherever you live, but where you are matters, too.

Solar Battery Storage System Cost Factors

There are many factors to consider when calculating your total solar battery project cost. Here are the biggest factors that can impact your budget:
- Energy capacity: A major cost factor is how much energy your battery can store. Units that store more kWh cost more than units that store less.
- Power: Your batterys potential output is shown in kilowatts and determines how much electricity the battery can generate in a specific moment. Storage systems that are more efficient at storing energy are likely to cost more.
- Battery chemistry: Lithium-ion phosphate batteries cost more than lead-acid batteries, with LFP batteries costing approximately 30% to 50% more than some of the cheapest batteries on the market.
- Brand: One brand might charge more than another, but it might also have installation prices tacked onto the total cost that saves you money.
- Quality: High-quality materials will run higher than low-quality materials.
- Upgraded features: Inbuilt inverters, smart technology, and other upgrades may add to the cost of your battery unit.
- Installation company: Some battery brands do not come with installation, as theyre solely for solar equipment. You may have to purchase the battery through the manufacturer and then find a separate installation company.
- Retrofitting an existing system: Youll pay more to have a battery added to an existing solar panel than if you installed them at the same time.

Size And Shape Of Your Roof
This one is a double whammy. The contours of your roof impact both the number of solar panels youll need to generate the necessary energy for your home and the labor involved in installing them for maximum efficiency. For example, gabled roofs with high peaks create lots of nooks and crannies for shadows, and they can be difficult for solar installers to navigate.
Average Monthly Energy Usage
This is the big one, if were being honest. Your energy bill will determine the size of the solar system you need therefore the number of panels you will need. While the average U.S. residential solar system is in the 5-kilowatt range, your family might be especially thrifty, meaning you might need only 4 kW to power your 2,000 square foot home.6 On the other hand, if you have a large family that entertains often and has installed lots of amenities in that same 2,000 square foot home, you might need an 8 kW system and that will cost more.
